摘要： A fully pigmentable, non-asphalt based, sealant composition for sealing cracks and joints in roads, streets, highways, sidewalks, pavements, and other concrete and asphalt surfaces. The pigmentable sealant is produced by (i) forming a non-asphalt base blend which contains a high concentration of a rosin ester material, (ii) neutralizing the color of the base blend using one or more color neutralizing materials, (iii) pigmenting the color-neutralized base blend to a desired final color, and (iv) adding one or more polymers to the pigmented blend to provide enhanced mechanical properties.
